can you please clarify what you mean, do you mean that the front heater blows cold but the rear blows hot or do you mean that when the heating is on cold it blows hot? many thanks paul
the heater blows warm air when fan is on low but blows cold air when fan is turn to higher setting
An automobile's heater that blows only cold air could either be a faulty thermostat or, more likely, a faulty heater core. A trip to a mechanic or shop that specializes in radiator and cooling system repair should be able to diagnose and repair any problems.
Heater core changed three years ago,I changed Thermostat Heater still blows cool air.
No fuse for those symptoms. Could be low on coolant. Bad thermostat. Plugged heater core (my guess). Temp blend door problems.
Get the air out of your heater core.
Could this be 2 separate problems?Stuck in defrost modeNo heatSee "Related Questions" below for more about both
The heater core is plugged. Blow it out with a compressor. If that does not work replace the heater core.
The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
heater hoses might have been disconected
